Abstract: This invention relates to a multilayered film for use as in-mold label, comprising: a core layer having a first surface and a second surface, the core layer being comprised of a polymeric mixture and particulate solids dispersed in the polymeric mixture; and an ink-printable layer overlying the first surface of the core layer; the film being formed by co-extruding the core layer and ink-printable layer to form the multilayered film, hot-stretching the film at a temperature above the expected service temperature of the label to provide the film with a machine direction orientation, the density of the film being reduced by about 10% to about 25% during hot-stretching, and annealing the film at a temperature above the expected service temperature of the label; the film having a machine direction Gurley stiffness value in the range of about 30 to about 120, a machine direction shrinkage of less than about 3%, and a machine direction shrink tension at 200° F. (93.3° C.) of less than about 100 psi.

Abstract: This invention relates to a multilayered thermoplastic film comprising: a thermoplastic core layer having a first side and a second side, the core layer comprising: a polyolefin having a density in the range of about 0.89 to about 0.97 grams per cubic centimeter; a second polymeric material selected from ionomers derived from sodium, lithium or zinc and an ethylene/methacrylic acid copolymer, and a combination thereof, and a light stabilizer; an abrasion and scuff resistant clear first thermoplastic skin layer overlying the first side of the core layer, and a clear second thermoplastic skin layer overlying the second side of the core layer, both skins containing light stabilizer. The composition of the core layer is different from the composition of the skin layers, and the core layer and the skin layers are characterized by the absence of PVC.

Abstract: A method of making a high gloss, multilayered thermoplastic film by pinning the extruding the molten thermoplastic film material onto a polished casting roll having a mirror finish. The thermoplastic film produced by this method has a superior gloss finish and has a ratio of distinctness of image in the machine direction to distinctness of image in the cross direction in the range of 1.3:1 to 1.0:1, and has a 20° gloss in the machine direction and the cross direction of at least 40.

Abstract: This invention relates to an imaged receptor laminate, comprising: a thermoplastic core layer having a first side and a second side; a thermoplastic skin layer overlying said first side of said core layer, said skin layer comprising a major amount of a thermoplastic copolymer or terpolymer derived from ethylene or propylene and a functional monomer selected from the group consisting of alkyl acrylate, acrylic acid, alkyl acrylic acid, vinyl acetate and combinations of two or more thereof, said skin layer having a melting point in the range of about 50.degree. C. to about 120.degree. C., said core layer having a melting point that is higher than the melting point of said skin layer; and an electrostatically formed and developed image adhered to said skin layer. In one embodiment, a dielectric layer overlies the toned image and the skin layer. In one embodiment, a conductive carrier sheet overlies the foregoing dielectric layer.

Abstract: Olefin polymer films composed essentially of a copolymer of a major proportion of ethylene with a minor proportion of a higher .alpha.-olefin monomer and an effective amount of a tackifying agent are provided which have unusually high Elmendorf tear strength in the machine direction, a good balance of machine direction to transverse direction Elmendorf tear strengths, and excellent cling properties. Such films are exceptionally well suited for use as a stretch/cling film in various packaging and palletizing applications.
